IMPROVEMENT IN ELSlRO-MAGNETIC GAS-BURNERS.

Specification forming part of Letters Patent N0. 204,826, dated June l1,1878; application filed May 3, 1878.

To all whom it 'may concern:

Be it known that I, WILLIAM W. JACQUES, of Newburyport, in the county ofEssex and State of Massachusetts, have made certain Improvements inElectro-Magnetic Gas-Burners 5 and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawing, and to theletters of reference marked thereon, which form a part of thisspecification, and in which- Figure l is a side view of my improvedelectro-magnetic gas-burner. Fi g'. 2 is a vertical section, partly inside view; and Fig. 3 is a detailed view of the gas-tube openin g andclosing valve, partly in perspective and section.

The same part in the several figures is denoted by the same letter.

The object of this invention is to provide a gas-burner in which theflow of gas is controlled by an electro-magnetic pillar or body,

and a valve of such material and in such manner that it can bemanufactured at a very small cost, and at the same time will bedurableand free from liability to get out of order or require repairing; and itconsists of an electromagnet suitably connected with a battery andinterposed between the burner and a valve, an arm of pipe or tubeconnecting with the gaspipe at a point below the valve and extending upin proximity with the burner-tip or orifice, and provided with a deepcup or cylinder around the jet or flame issuing therefrom, substantiallyas hereinafter more particularly set forth.

In the annexed drawing, A is a section of non-magnetic material,threaded internally at its lower end to permit of its attachment to thepipe of the gas-iixture, to the pipe pro jecting from the wall of thehouse, or to the pipe extending up through a lamp-post.

Around the inner circumference of this pipe A is an annular flange orseat, c, upon which the stem of the valve of soft iron B rests, asclearly seen in Fig. 3. The valve is made of soft iron and conical inshape, and its top surface is coated with some non-magnetic substance toprevent the so-called sticking of the valve and to insure a more perfectclosing of the opening e.

C is the electromagnet, made of soft iron, with a narrow centralpassage, c, through it for the passage of the gas, screw-threaded atboth ends, the thread or screw on its lower end to permit of itsattachment to the valve pipe A, the latter having an inner female screw,and the screw on its upper end to 'permit of the attachment thereto ofthe burner D, of the usual construction.

Around the electro-magnet is coiled the wire E, connecting with abattery. Connecting with the tube or pipe A, at a point below the valveB, is a bent tube or arm of pipe F, hav ing attached to its upper end(which extends up in proximity with the burner D) a deep cylinder orcup, f, to inclose and shield its flame.

The operation is as follows: A current of electricity being' transmittedthrough the wire E around the magnet C, it (the latter) will attract andlift the valve into contact with itself and close the. entrance to itspassage c, and thus cut off the flow of gas and extinguish the light.Break the current, and the attracting power of themagnethavin gthusbeenremoved, the valve will fall therefrom and thus eifect the openingof the passage of said magnet and permit of the ilow of the gas, whenthe latter will be instantly lighted by the flame of the pipe F.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In an electro-magnetic gas-lighting appa-` ratus, the soft-iron portionof the body ofthe burner interposed between the valve and burnertip,provided with a helix through which a closed circuit is maintained toclose the flow of gas to the main burner by means of an armature-valve,which valve is allowed to fall, thereby allowing the flow of gas bybreaking the previously-closed circuit.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in the presence of two witnesses.

WILLIAM W. JACQUES.
